[Ipopt] eval_grad_f , eval_jac_g, eval_h

[Alberto Jorrín Rodríguez]

Dear mates,

   I would like to know if it is absolutely neccesary to declare the functions "eval_grad_f ", "eval_jac_g" and "eval_h" for introduce the gradient, constraints jacobian and hessian and if exist the possibility of telling Ipopt that he must compute this 3 informations automatically using the objective function expression and the constraints expressions only.

Thanks a lot

Regards
